fix resource registry, again

[dholth]

It looks like set_*_resources expects each resource as a new positional argument. To fix, change all the .resources.default_resources to sequences and use * as below.

http://deform.readthedocs.org/en/latest/api.html#deform.widget.ResourceRegistry.set_css_resources

deform_bootstrap.init:

def add_resources_to_registry():
"""
Register deform_bootstrap widget specific requirements to deform's
default resource registry
"""
registry = Form.default_resource_registry
for rqrt, versions in default_resources.items():
for version, resources in versions.items():
registry.set_js_resources(rqrt, version, *resources.get('js'))
registry.set_css_resources(rqrt, version, *resources.get('css'))

Hey Daniel. Would you kindly send a pull request, it's not entirely clear to me what the changes need to look like. Also, can you specify which version of deform we're targeting with this change. Thanks.
